Re: Planning for the next release

[Ludovic Courtès]

Hi Leo!

(sirgazil: this is about providing a ready-to-use VM image of GuixSD for
download, in addition to the installation image.  See at the bottom.)

Leo Famulari <address@hidden> skribis:

Sounds good.

As discussed on IRC, there was a typo fixed in
6344e959ea45c283a0c7a2091f0959f8e09a198d.  As for offloading, the target
assumes that the user has set it up correctly.

I’ll add a guix.scm there.

OK.  I think this commit can be squashed with the next one.

What about explicitly mentioning VPS, as in:

- If you’d like to install GuixSD in a virtual machine (VM)
+ @cindex virtual private server (VPS)
+ @cindex VPS (virtual private server)
+ If you’d like to install GuixSD in a virtual machine (VM)
+ in a virtual machine (VM) or on a virtual private server (VPS)

?

So you need --system=$$system as well.  :-)

Otherwise LGTM.

sirgazil: do you think we should add a special icon or something for the
VM image?

Otherwise LGTM!

Thanks,
